The present article is a fluid control valve used, for example, toimmediately discharge a large amount of pressure fluid at high speed forwiping off dust attached to a bag filter of a dust collector. The fluidcontrol valve includes: a body having two pressure fluid inlet/outletports; and a bonnet attached on an upper part of the body (See Referencedrawings 1 and 2). The two pressure fluid inlet/outlet ports communicatewith each other via a not illustrated passage formed inside the body. Inthe passage, a not illustrated valve body integrally formed with adiaphragm is provided. When using, for example, a not illustratedpressure fluid supply source such as an air tank is connected to one ofthe pressure fluid inlet/outlet ports, and a not illustrated injectionpipe connected with an upper opening of the bag filter provided insidethe dust collector is connected to the other of the pressure fluidinlet/outlet ports. In this state, when the pressure fluid is suppliedto the present article, the valve body is opened according to thepressure of the pressure fluid, and the pressure fluid is injectedinside the bag filter via the injection pipe. The injected pressurefluid causes impact on the bag filter to remove the dust attached to anouter periphery of the bag filter.

CLAIM The ornamental design for a fluid control valve, as shown anddescribed.
